Alkaline batteries versus zinc batteries

Which batteries should you use in low drain appliances such as a TV remote control or a clock? And which ones are ideal for your dect phone? Do you have to choose the zinc batteries or are the alkaline cells better? But what is the main difference between both batteries? An overview below. 

The main difference between a zinc battery and an alkaline battery is the type of electrolyte used in both batteries. Zinc batteries are mostly composed of ammonium chloride while the alkaline batteries use potassium hydroxide. However, these technical specifications don't say much more about the usage of the batteries. That's why we are now going to take a closer look at the capacity, the benefits and the applications for zinc batteries and alkaline batteries. 

Benefits of Alkaline

Alkaline batteries have a higher energy density and a longer shelf life – the time a battery can remain in storage without losing any of its capacity. The Alkaline Battery Technology is one where intensive research and development have led to three unique technologies. The Panasonic Alkaline batteries first of all have an Anti-Leak Protection to prevent damage to appliances. The reason for leakage is the chemistry of the battery that changes and gas that is generated when the battery discharges. 

Next to this, there is also a specially designed coating inside the batteries that reduces contact resistance for greater reliability. Lastly, the Alkaline cells have an Extra Power Formula to maintain power for a longer period in high-drain devices. 

Appliances for Alkaline

Because alkaline batteries provide more energy than zinc batteries, you should use the alkaline cells for appliances such as tooth brushes, toys and game controllers.

Benefits of Zinc

The Panasonic Zinc Carbon batteries are widely used worldwide. They are made of a simple experienced and reliable technology and they have an excellent price versus quality ratio. The battery is economical in terms of cost per hour for low drain devices. 

Appliances for Zinc  

These batteries are a reliable source of power for appliances that consume little energy. In appliances like remote controls for television, clocks, smoke detectors and torches, you should use the Zinc batteries because of the low energy consumption. This will lead to being able to use the appliances for a longer time for the same money.

As expected, the capacity of both batteries is different. Because of the composition, an alkaline battery delivers more energy than a zinc battery. The only consequence of this is that both batteries should be used in different applications. 

Other batteries 

Are you using other applications than these mentioned above? Panasonic has a whole range of batteries ideal for your devices.  


For products like dect phones, flash cameras, toy cars and even game controllers, which are frequently used high-drain applications, the rechargeable EVOLTA battery is ideal. This rechargeable battery is designed for high-power applications (min. 2450 mAh for AA batteries and 900 mAh for AAA batteries) and retains up to 80% of the original capacity after they have been in storage for a year. The Panasonic Evolta cells are also resistant in cold weather conditions, so they are perfect when you have to use a photo camera in temperatures of -20°C. 

Occasional users

Occasional users should use another Panasonic Rechargeable Ready to Use battery. These are perfect for batteries with a minimum of 1000 mAh for AA batteries and telephone batteries. You can also use them in a computer mouse, remote control and dect phone. 

Frequent users

Are you a frequent battery user? Then the Panasonic Ready to Use (Rechargeable) battery with min. 1900 mAh (AA) or 750 mAh (AAA) is ideal. Use these batteries only in appliances like torches, tooth brushes, computer mouses and remote controls. 

For high drain appliances

Next to the Evolta for heavy users, there is another rechargeable battery with a high capacity for high-drain devices (Ni-MH 2700 – Ni-MH 1000) like flash lights, game controllers, torches and toys.
